Answer:
- 2x - 7y
Step-by-step explanation:
Given
- (4x + y) + 2(x - 3y)
Distribute both parenthesis, noting that the first is distributed by - 1
= - 4x - y + 2x - 6y ← collect like terms
= (- 4x + 2x) + (- y - 6y )
= - 2x + (- 7y) = - 2x - 7y
Let the fist integer be x, the second is x+20
the product of the numbers is:
x(x+20)
the sum of the numbers is:
x+x+20=2x+20
the sum of the above operations will give us:
2x+20+x^2+20x=95
x^2+22x+20=95
this can be written as quadratic to be:
x^2+22x-75=0
solving the above we get:
x=3 and x=-25
but since the integers should be positive, then x=3
the second number is x+20=3+20=23
hence the numbers are:
3 and 23
